- REBOUND (github.com/hannorein/rebound)
REBOUND is an N-body integrator, i.e. a software package that can integrate the motion of particles under the influence of gravity. The particles can represent stars, planets, moons, ring or dust particles. REBOUND is very flexible and can be customized to accurately and efficiently solve many problems in astrophysics.
- 5 steps to N-body simulation (alvinng4.github.io)
This is a series of tutorials inspired by the course “CFD Python: 12 steps to Navier-Stokes”. The goal is to teach beginners how to write fast and clean N-body gravity simulations code in Python.
- n-body problem (Wikipedia)
In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. Solving this problem has been motivated by the desire to understand the motions of the Sun, Moon, planets, and visible stars. In the 20th century, understanding the dynamics of globular cluster star systems became an important n-body problem. The n-body problem in general relativity is considerably more difficult to solve due to additional factors like time and space distortions.
